India, May 20 -- The Government of India has issued a release:
A novel way to detect hidden turbulence in the Sun's outer atmosphere or corona could help scientists gain new insights into the long-standing mystery of why the corona is much hotter than the Sun's visible surface.
The Sun's outer atmosphere, the corona, is filled with magnetic structures that constantly sway as waves travel along them. Among the most common of these are propagating transverse magnetohydrodynamic (MHD) waves, often described as Alfvenic or kink waves. These waves make coronal structures oscillate sideways as they move outward along these magnetic structures.
Spectroscopically, such waves are known to produce alternating red and blue Doppler shifts, signatur...
